Interest in the quantitative arithmetic of Campana orbifolds has been further sparked by the recent work [1]}, in which Pieropan, Smeets, Tanimoto and Várilly-Alvarado formulate a Manin-type conjecture for Fano Campana orbifolds. The authors establish their conjecture in the special case of vector group compactifications, using the height zeta function method developed by Chambert-Loir and Tschinkel in [2]} and [3]}.
